Q1. A liquor of 0.30 mole fraction of benzene and the rest toluene is fed to a continuous still (distillation column) to give a top product of 0.90 mole fraction benzene and a bottom product of 0.95 mole fraction toluene. If the reflux ratio is 5.0, how many plates are required: (a) if the feed is saturated vapour? (b) if the feed is saturated liquid? Mole fraction of benzene in liquid 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 Mole fraction of benzene in 0.22 0.38 0.51 0.63 0.7 0.78 0.85 0.91 0.96 vapour

Define Accuracy and give two examples of how this can be expressed. Define Hysteresis.
